Out of the lot the person I like the most is Clarkson - he is so refreshing in the PC dominated world and is not afraid to make himself appear like a fool. And even when joking he seems to be talking sense.
Russel Brand I am afraid is just an irritating talentless berk. But then he is actually quite bright, or at least well read. I think when he has grown up he may be suitable for TV.
Jonathan Ross is an OK interviewer but is good on the film shows, I do like his enthusiasm though - he does play an act and part of it is to send himself up.
Carol Thatcher is basically mad but I do find her an interesting and likeable TV person, she is a traditional eccentric.
Gordon Brown - does his best to try to appear clever but to be honest I don't think he understands the economy, stealing money from pension funds was just downright evil and why did he not save during the boom years?
As to MPs I really hate - Wacky Jaquie, Ed 'dangle berries', Millipede, all proven to be untrustable.
I like a politician who says what he means and is not afraid of the image. This is why most people like Tony Benn regardless of their politics (we all have to thank him for keeping the Concorde project going), another favourite is Ken Clarke, but others I have found likeable are believe it or not Hague, Kennedy, Cable and Duncan*
* Not in that way of course!
